Do this and it will work. It sounds grouse and painful, but it doesn't hurt at all. First soak your feet in hot water with Epsom salts. If you have none, just use hot water. After about 15 minutes, take your feet out and dry them off. The take a metal finger nail file (or something of the same) and place the pointed end next to the hang nail and pry it upward, In other words at the side of the nail (usually the toe nail) between the toes place the pointed end next to the nail between the nail and the skin. Then pry the edge of the nail upward and hold it there for about 1 minute or so. It really doesn't hurt. Trust me. It really relieves the pain and last for a very long time.
If u have hangnails pick at them then quickly put some lotion on ((if theres way too much blood rub on some alchol))
if u dont have any lotion put on some olive oilto help the sensative skin
